thanks a lot, i have cleaned the bolt and entirely stripped the gun after about every 3 days of play, that includes solenoid cleaning. also when i clean the bolt and other internals and i use only shocker lube on it which is the smart parts lubricant you are supposed to use. all internals are in great shape,, no co2 ever used in it, actually i have never even put a high pressure nitrogen tank into the gun. the reg is very consistent, it is cp which is the best there is and i have cleaned and lubed the piston of the reg to allow a shot consistencey of about +/- 6 fps. and i will include all original boxing, parts, spare parts, field tools, and instruction manual. i will even throw in 2 tubes of new shocker lube for giggles and kicks. (btw u can only use shocker lube on smart parts guns or else the warranty is automatically voided and the gun will not work properly). if u are looking tog et into tourny for a decent price here it is. the ion is very efficient, getting about 7050 shots off the 45/45 tanks shooting at 150 psi per shot. You can buy a new shocker for $600, or you can buy this for $500, but u will get the gun, cp reg, freak barrel, cp accesories, new halo b, 45/45 lp crossfire nitro tank, a 3 pack proto pod set with dye and cp pods, 2 tubes of shocker lube($8 per tube) all original packaging and spare parts, and all together u have a sick gun setup that will handle any tourny series fine. i can tell no difference in the performance of this gun and timmys, e-cockers, shockers, nerves, dm's or any other high end tourny gun.
